TROLLEY-POLE HEAD.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application-filed October 28,1905. Serial No. 284,810.

To all whom/ it mar/y concern:

Be it known that 1, WILLIAM J. WAGNER, a citizen of the United States,residing at East Bradford, in the county of McKean, State ofPennsylvania, have invented certain new and useful Improvements inTrolley- Pole Heads; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

- This invention relates to trolley pole heads.

One object of the invention is to provide a simple, inexpensive,durable, and efficient device of the character stated. 9

Another object of the invention resides in the provision of opposingclamping members adapted to yield-ably engage each other to embrace thetrolley-wire in such manner that the usual brackets and circuit-breakersmay be readily passed.

TVith these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and moreparticularly pointed out in the appended claims, it being understoodthat changes in the form, proportion, size, and minor details may bemade within the scope of the claims without departing from the spirit orsacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is a side elevation of my invention. Fig. 2 isa top plan view. Fig. 3 is an end view. Fig. 4 is a detail view of onepair of semicylindricah shaped feed-wire-embracing members. Fig. 5 is adetail view of the pair of arms with which the members of each pair ofsemicy lindrical-shaped members are connected.

Referring now more particularly to the accompanying drawings, thereference character 2 indicates a trolley-pole, which is enlarged at itsouter end and bifurcated to form spaced ears 3 for the receptiontherebetween of a trolley-wheel 4, whose axle 5 is reduced at its endsfor engagement in the slots 6 of the springplates 7 and 8, which holdthe axle adjust-ably in their slots by means of the pairs of nuts 9 and10 cooperating therewith and the reduced ends of the axle. The lower endof each spring-plate 7 and 8 is bent outwardly, as shown at 11, forengagement with the correspondingly-perforated lugs 13 of the brackets14 and 15. The arms 16 and 17 of the brackets 14 and 15 each haveconnected therewith a semicylindrical-shaped trolleywire-engaging member18 and 19. These members 18 and 19 adapted to form a cylindrical-shapedmember when secured together provided with flaring ends 20, which arecut away at 21 to form a V-shaped notch 22 at each end of each completecylindricalshaped member, so that the semicylindrical members 18 and 19of the complete cylindrical member may readily separate from each otherwhen contact thereof is made with a bracket, circuit-breaker, or thelike.

The trolley-wire is indicated by the reference character 23, and it willbe seen that a pair of clamping members 18 and 19 is arranged in frontand in the rear of the trolleywheel 4. Now in order to hold theseclamping members 18 and 19 in yieldable engagement with each other thearms 16 and 17 of each bracket are each provided at its upper end withthe semicylindrical fingers 26 and 27, adapted to embrace thesemicylindricalshaped trolley-wire-engaging members 18 and 19 and to besecured fixedly thereto. It will thus be understood that the arms 16 and17 of each bracket are in spaced relation, and in order to connect themtogether so that they may be operated to move the semicylindrical-shapedmembers 18 and 19 away from each other I provide each arm of eachbracket with a lug 28 and 29, respectively. The lug 29 is provided witha curved slot 30, while the lug 28 is provided with a perfora tion. Thelugs 28 and 29 are designed to overlap each other and are held in suchover lapped relation by means of a suitable bolt 32 passed through thesaid perforation and the slot 30 of the respective lugs. Obviously byreason of the peculiar connection of the overlapped lugs they cannotmove one in advance of the other, but are permitted a slight lateralplay with respect to each other for downward pull upon theoperating-rope 36 the purpose of moving the semicylindricalwill separatethe semicylindrical members 18 and 19 when desired.

What is claimed is 1. A trolley-pole head comprising a pole having aWheel mounted at its upper end, brackets arranged upon opposite sides ofthe trolley-pole, a connection between the ends of the aXis of thetrolley-Wheel and said brackets, a semicylindrical member secured ateach end of said brackets to form cooperating pairs of members toembrace the trolley- Wire, and means connecting the brackets whereby thepairs of wire-embracing members may be separated with relation onemember with its companion member.

2. A trolley-pole head comprisin a pole having its upper end enlargedand bi mated to form spaced ears, a trolley-wheel mounted between saidears, a pair of brackets arranged upon opposite sides of thetrolley-pole, each bracket having a projection intermediate its ends, aspring-plate connected to each projection of each bracket and providedwith a slot for the adjustable sup ort in the latter of the axle of thetrolley-w eel, pairs of trolley-Wire-engaging members connected to thesaid brackets and arranged for engagement with the trolley-Wire in frontand in the rear of the trolley-wheel, and means connected to thebrackets whereby the latter may be moved to operate the Wire-embracingmembers to permit disengagement of the latter with the trolley-Wire. I

In testimony whereof I aflix my signature in presence of two Witnesses.

WM. J. WAGNER.
